  5. 3. Radiant Textiles : Designing electromagnetic textile systems

    Author : Erin Lewis; Tincuta Heinzel; Högskolan i Borås; []
    Keywords : HUMANIORA; HUMANITIES; smart textiles; electromagnetism; textile design; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Abstract : To regard the electromagnetic domain of conductive textiles is to unlock a realm of expressive possibilities. The underexplored area of the electromagnetic domain in con­ductive textiles implies that numerous computational and electronic textiles created thus far possess untapped capabilities. READ MORE

  6. 4. Radiant Textiles : A framework for designing with electromagnetic phenomena

    Author : Erin Lewis; Delia Dumitrescu; Katharina Bredies; Högskolan i Borås; []
    Keywords : HUMANIORA; HUMANITIES; smart textiles; interaction design; textile interaction; textile; electronic; electromagnetism electromagnetic; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Abstract : The design of smart, interactive, computational, and electronic textiles involves working with unknown variables that expand the tangible dimensions of textiles. Non-visual concepts such as electromagnetic fields, electrical current, computational code, and the temporal attributes of materials that exhibit dynamic qualities require that textile designers be able to perceive and manipulate domains of the textile that extend beyond its conventional forms of expression.

  7. 5. Hybrid Methods for Computational Electromagnetics in Frequency Domain

    Author : Stefan Hagdahl; Björn Engquist; Lars Pettersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maxwell s equations; Geometrical Theory of Diffraction; Smooth Surface Diffraction; Boundary Element Method; Hybrid methods; Electromagnetic Scattering; Numerical analysis; Numerisk analys;

    Abstract : In this thesis we study hybrid numerical methods to be used in computational electromagnetics. The purpose is to address a wide frequency range relative to a given geometry. We also focus on efficient and robust numerical algorithms for computing the so called Smooth Surface Diffraction predicted by Geometrical Theory of Diffraction (GTD). READ MORE
